Ceilings can be dangerous places for Fire Alarm Heat Detectors.  Anything from basketballs to broom handles can threaten the safety and proper operation of a detector.   THERMOFLEX offers a choice of protective guards that can be installed on existing or newly-installed units in areas such as gymnasiums and janitors closets.  THERMOFLEX also provides an aesthetic solution to small errors made during installation that may require an attractive “cover up” without affecting the rating or proper operation of the unit.

Part # 150 Large Wire Guard  This strong, welded guard protects the entire detector and mounts directly onto the ceiling surface.  Sections of the base can be cut out to accommodate conduit connected to the electrical box when the unit is surface mounted.  The # 150 is ideal for use in gymnasiums and other sports facilities where there is a potential for damage from flying objects.  Auditorium stages with storage spaces underneath, are also suitable locations for this heavy duty guard.  THERMOFLEX provides an adapter for the Model FD 200  Portable Test Unit that allows for the proper testing of the rate-of-rise detector protected by the guard.

Part # 152  Cover Plate Guard   This is a lighter weight guard that can be retro-fitted to an existing detector located in an area where a moderate potential for damage exists.   The guard is riveted to a standard cover plate that replaces the existing cover.  This guard is suitable for janitors’ closets and machine rooms, and any area where a low ceiling will increase the danger of the unit being struck inadvertently. 

Part # 172 &174 Trim Rings  Occasionally, a ceiling tile will be cut incorrectly, or an electrical back box will not properly align with a ceiling opening.  THERMOFLEX offers two trim rings that will solve the problem and maintain the aesthetics of the ceiling surface

Part # 172  is an extended anodized aluminum trim ring, outside diameter (OD) of 5 5/8 “ (14 cm.).  This ring extends the overall  radius by 5/8”  (1.5 cm.).

Part # 174  (shown left),  is a larger trim ring whose OD is 6.5” (16.5 cm.), extending the overall radius by 1.0” (2.5 cm.).

The original style detector with the aluminum adapter plate and the newer Standard Heat Detector can both be used with these trim rings.
